Spe Formation Evaluation | 1993

The Effect of Wellbore Condition on Wireline and MWD Neutron Density Logs

David F. Allen; David L. Best; Michael Evans; Jacques M. Holenka

The wellbore condition and its corresponding effect on log readings must be assessed and corrected for during log quality control and formation evaluation. Differences arise between measurement-while-drilling (MWD) and wireline neutron density, photoelectric factor (PEF) logs made in the same well because the two systems respond differently to the wellbore environment. Differences also occur because of changes in wellbore condition over time
